Hmm, I'm not sure - I managed to burn several of these disks using growisofs, and then mount the disks on my Mac (as well as on this linux box) so I *think* the media are OK?
Anyway, attached is the output from "cdrecord-ProDVD dev=0,0,0 -atip" and it doesn't look good... although I'm not sure what it is telling us.
BTW: Are there any "dangers" with using the "-atip" option?
Since I used it, I haven't been able to mount *any* DVD media on this drive - it was working OK before (I had been checking through the backups I made on Wed. to make sure they were *still* OK) but after trying the -atip test I now can't access *any* DVD on this drive...
not even DVD-ROM or movies.
I *can* still mount CD's though.
It's probably just a coincidence, but I thought I'd better ask in case there were any known issues, as at present my *cheap* DVD burner has turned in to an *expensive* CD reader...
Which is inconvenient, to say the least!
Thanks again. Cheers for now, -atip output attached,
